Scope:
This document applies to shell boilers with volumes in excess of 2 l for the generation of steam and/or hot water at a maximum allowable pressure greater than 0,5 bar and with a temperature in excess of 110 °C.
For the purpose of this document the following pressurized parts are included:
— the shell boiler as one entity of pressure equipment including all the pressure parts from the feedwater/hot water inlet (including the inlet valve) up to and including the steam/hot water outlet (including the outlet valve or, if there is no valve, the first circumferential weld or flange downstream of the shell boiler or if applicable the outlet header);
— all superheaters, economizers and interconnecting piping;
— additionally, the piping that is connected to the boiler involved in services such as draining, venting, desuperheating, etc., up to the first isolating valve or, if there is no valve, the first circumferential weld or flange downstream of the shell boiler or if applicable the outlet header/piping.
This document does not apply to the following types of boilers and equipments:
a) water-tube boilers;
b) non stationary boilers, e.g. locomotive boilers;
c) thermal oil boilers;
d) boilers where the main pressure housing is made of cast material;
e) pumps, gaskets, etc;
f) brickwork setting and insulation, etc.
NOTE 1 Further information on shell boilers is given in Annex A.
NOTE 2 Stainless steel boilers are covered by EN 14222:2021.

Solid biofuels - Determination of bulk density (ISO/DIS 17828:2024)
Scope:
This revised International Standard describes a method for determining bulk density of solid biofuels with the use of a standardized measuring container. This method is applicable to all pourable solid biofuels with a nominal top size of maximum 63 mm. while the maximum particle length is 200 mm. For fuels with a nominal top size larger than 63 mm, a different method is described.

Vehicles, boats and internal combustion engines - Radio disturbance characteristics - Limits and methods of measurement for the protection of off-board receivers
Scope:
The limits in this International Standard are designed to provide protection in the frequency range of 30 MHz to 1 000 MHz for off-board receivers. Compliance with this document might not provide adequate protection for receivers nearer than 10 m to the vehicle, boat or device.
This document applies to the emission of electromagnetic energy that can cause interference to radio reception and which is emitted from:
1) vehicles propelled by an internal combustion engine (ICE), electrical means or both (see 3.1.30);
2) boats propelled by an ICE, electrical means or both (see 3.1.4). Boats are to be tested in the same manner as vehicles except where they have unique characteristics as explicitly stated in this document;
3) devices equipped with ICE (see 3.1.8). In the case of hybrid devices (e.g. equipped with both ICE and traction batteries), only the ICE mode is included in this document;
4) inboard and outboard boat engines/ motors [i.e. equipped with ICE, electric motor (EM), or both], when marketed independently.
See Annex D for a flow chart and a list of examples to help determine the applicability of CISPR 12.
This document does not apply to aircraft, household appliances, medical devices, traction systems (railway engine or locomotive, streetcar or tram and electric trolley bus), vehicle / boat / device off-board chargers or to incomplete vehicles/boats/devices. In the case of a dual-mode trolley bus (e.g. propelled by power from either AC/DC mains or an ICE), the ICE propulsion system is included, but the EM propulsion portion of the vehicle is excluded from this document.
In addition, domestic helper robots, such as household cleaning robots, hotel service robots and personal safety robots are also excluded from the scope of this document.
NOTE 1 Other than inboard or outboard boat engines/ motors that are marketed independently, this document does not apply to components or incomplete products, such as an ICE, an incomplete vehicle/boat that has not yet been fitted with an ICE or EM, or spare parts. This document only applies to the final product, which is equipped with all necessary parts and components to be able to function as intended.
NOTE 2 Appliances without ICE for typical housekeeping and service functions in the household and similar environment are covered by the requirements of CISPR 14-1.
NOTE 3 Protection of receivers used on board the same vehicle as the disturbance source(s) are covered by CISPR 25.
This document does not prescribe measurement methods or limits for conducted disturbances, for the charging mode of operation, where the (electric or hybrid) vehicle/boat is connected to power mains, either directly (i.e. plug-in vehicle or boat) or indirectly (i.e. wireless power charging). The user is referred to appropriate IEC and CISPR standards, which define measurement techniques and limits for this condition.
NOTE 4 See IEC 61851-21-1 for road vehicles and IEC 61000-6-3, IEC 61000-6-4 and IEC 61000-6-8 for other types of vehicles or boats.
The emission requirements in this document are not applicable to the intentional transmissions from a radio transmitter, as defined by the ITU-R, including their spurious emissions.
Equipment that is covered by other CISPR product and product family emission standards are excluded from the scope of this standard, except where they include ICE(s). In the latter case, the equipment shall comply with this standard in all modes of operation where the ICE(s) is(are) active.
NOTE 5 The other CISPR product or product family emission standard might also apply to the equipment for those modes of operation where the ICE(s) is (are) not active. In case the ICE(s) is (are) always in operation, the other CISPR product or product family emission standard might still apply, for verifying the emissions from the other components and circuitry of the equipment.
Annex B and Annex C contain methods to evaluate the disturbance characteristics of high voltage ignition systems.
Annex H lists work being considered for future revisions.
